Michael J. Demkowicz
Assistant Professor of Materials Science and Engineering
MIT Department of Materials Science and Engineering
Professor Demkowicz will present two examples that illustrate how controlling the structure of interfaces may be used to enhance materials performance in extreme environments. The first concerns materials in future fusion reactors, which may fail due to copious He implantation. Demkowicz will describe a way of mitigating He-induced damage by trapping He at heterophase interfaces. In the second, he will discuss how grain boundary engineering may reduce susceptibility to Hydrogen embrittlement in materials used in deep oil wells.
